简单介绍


ossila材料2PTZBN  的详细介绍

2PTZBN是一种多共振热激活延迟荧光(MR-TADF)绿色发射体,核心为DABNA-1三雅基硼。两个与氮原子相对的重硫原子嵌入以桥接周边苯环,形成更刚性结构。通过将非金属硫原子融合到多共振B-N框架中,它可以将发射体的反向系统间交叉(RISC)过程加速至2.8×105 s-1 in toluene due to larger spin-orbital coupling (SOC) values and smaller singlet-triplet energy splitting (ΔEST) while compared with the oxygen incorporated green MR-TADF emitter 2PXZBN (PXZ-BN).

OLED device based on 2PTZBN as the active layer dopant and DMIC-TRZ as the host demonstrates maximum EQE of 34.6% with low turn-on voltage below 2.5 V and extremely high luminance over 100,000 cd m-2.
